LOOM-LAY MOUNTING.

Application led June 3, 1926, Serial No. 113,368, and in Germany .Tune17, 1925.

This invention has reference to im rovements in the operation of loomsan it is particularly intended to devise means of utilizingsubstantially the entire amount of the kinetic and oscillating energyimparted to the lay or vhatten of a loom, so as to arriveat a greateconomy of power as compared with the operation of looms in accordancewith previous constructions. In view thereof the layor batten inaccordance with this invention is not merely oscillated by crankoperation or the like, but the lay or hatten is spring-actuatinglyarranged and in such a manner that the rocking movement in one directionis automatically succeeded by a spring-actuatingly occurring rockingmovement in the opposite direction, such movement taking place in phasewith the natural oscillating frequency of the device, so thatsubstantially only enough power is required to maint-ain the oscillatingmovements and suficient for the beating up of the filling threads by thelay or hatten.

In rthe constructions of lays, as at presentemployed the kinetic' energyproduced by the mass of the lay or hatten in its rocking movement had tobe destroyed twice in the driving operation, and on the other hand theentire mass of the lay had to be again twice accelerated, and in viewthereof a rather very considerable amount` of power was necessary whichis greatly reduced in the construction according to this invention. Bymeans of this new construction the amount of power required may bereduced to about 40 per cent with the additional ad vantage of a verymuch smoother movement of the loom.

The invention will be more `fully described with reference to theaccompanying drawing showing by way of exemplification one of thevarious possible forms of embodiment of the principles of my invention.

Fig. 1 shows a loom with a batten according to this invention inpartsectional view and Figure 2 is an elevation of the batten or laywith the frame of the loom in transverse section.

In the frame l of the loom the lay swords l or supports 2 of the lay orhatten are secured for oscillating movement in any suitable manner, thusfor instance, by means of angular clamps or the like. The lay swordspreferably comprise a plurality of stepped leaf springs of dierentlengths in accordance with the desired number of revolutions of the loomand with the mass of the lay.

The lay swords are connected in the usual manner by means of the laybeam 3 and the voperation may be effected as ordinarily by crank drive,it produces a higher degree of uniformity and thereby results in asmoother movement of the loom itself.

The spring acting movement of the lay may also be produced by otherspring acting elements, such as for instance tensional springs or coiledsprings mounted on the shaft of the lay, and other changes andmodifications in the selection and arrangement of parts may beintroduced without deviating from the spirit and scope of the invention,as particularly set forth in the appended claims.

I claim:

l. In a loom, a lay, a plurality of com bined superimposed leaf springsfixed at one end for oscillating motion and connected to the lay andconstituting lay swords, and driving means operatively connected to thelay.

2. In a loom, a lay, a resilient oscillatory support for the lay of leafspring construction, and driving means for oscillating said support.

3. In a loom, a lay, a spring support for the lay fixed at its lower endfor resilient oscillatory movements responsive to the oscillatorymovements of the lay, and a positive driving means for the lay operatingto tension the spring support on the forward driving motion of the lay.

4. In a loom, a lay, a spring sword normally oscillatable when tensionedthrough a range extending to equal degrees in opposite directions beyonda neutral plane, and means for moving such sword to and fro.

5. In a loom, a lay, a spring support for the lay, connected at itsupper end to the lay and at its lower end to the loom freine,4

said support being normally operated when tensioned for vibration tovibrate to equal degrees in opposite directions beyond a neu- 5tral'position, and drivingmeans for Vibrat- V ing said support.

6. In a loom, a frame, a,` lay, leaf spring v v supports for the laysecured at their upper ends to the ends of the lay and at their lowerends to the sides of the loom frame, 10 and driving means foroscillating the lay Y and supports;

In testimony whereof-I aflxr my signature. PAUL ESTERS.
